What molar quantity is associated with a 130*kg mass of water?

And what mass is associated with $1.82 \cdot m o l$ of $\text{sulfur dioxide}$? And what mass is associated with $0.0482 \cdot m o l$ of $C {H}_{2} C {l}_{2}$?

We use the quotient.....$\text{Mass"/"Molar mass"="Number of moles...}$

Explanation:

And so for $\text{water}$ we gots....

$\frac{130 \cdot k g \times {10}^{3} \cdot g \cdot k {g}^{-} 1}{18.011 \cdot g \cdot m o {l}^{-} 1} = 7218.2 \cdot m o l$

And for $\text{nitrous oxide}$ we gots....

(4.6*g)/(44.01*g*mol^-1)=??*mol

And for $\text{sulfur dioxide}$ we gots....

1.82*molxx64.07*g*mol^-1=??*g

And for $\text{methylene chloride}$ we gots....

0.0484*molxx84.93*g*mol^-1=??*g

Do you see what I have done with the quotient?
